Filed May 31, 1960, Ser. No. 32,635 1 Claim. (Cl. 140-122) .Our present invention relates to the broad class of manually operated implements and more particularly to a hanger-wire tieing tool.

While modernizing the interiors of old buildings having extremely high ceilings, or adding a false ceiling under the original one for improved lighting systems and/or decorating installations, it is customary to apply support members to the upper ceiling and suspend the false ceiling, or other architectural feature, by hanger wires attached to the support members. The ceilings to which the support members are secured are at such an elevation from the floor that without a ladder or scaffolding, the hanger wires cannot be twisted or tied to anchor them to the support members. Much time and therefore money is expended while moving a ladder from place to place or assembling and disassembling scaffolding to accomplish this function.

To provide a hanger-wire tie tool which will enable a workman to secure or tie the hanger wires to the support members quickly, easily and efiieiently While standing upon the floor of the room is the principle object of the present invention.

Another object of the present invention is to provide a tool of the class described which has removably assembled component parts easily assembled for use and disassembled for storage or transportation.

A still further object of the invention lies in the provision of a hanger-wire tie tool having a manually operable crank and a wire-twisting head at opposed ends of a torque arm which may be any length desired to enable the manipulator to reach ceilings of various heights.

Yet another object of the invention lies in the provision of a hanger-wire tie tool which is manufactured with facility from a minimum number of parts and which is not liable to become inoperative.

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts,

FIGURE 1 is an elevational view of the invention associated with a hanger-wire and showing a ceiling in cross section;

FIGURE 2 is a view of the head of the hanger-wire tie tool taken on a plane substantially indicated by line 22 of FIGURE 1;

FIGURE 3 is a top plan view of the head portion; and

FIGURE 4 is a modified species of hanger-wire tieing tool shown in perspective.

Having reference now more particularly to the drawing, the reference numeral indicates an existing ceiling construction into which is secured a support member 12. The hanger-wire 14 has a main portion 16' which is adapted to be secured to and support the false work (not shown). The hanger-wire has a tail portion 18, which in most instances is somewhat shorter than the main portion 16, but is a continuation thereof.

A tool which embodies the present invention has a hollow cylindrical or tubular torque arm 20 which is threaded at the upper and lower ends 21 and 22 to provide means for releasably securing complementary memhers. By way of example and not limitation, the torque arm may be conventional cast iron pipe threaded at each end to receive respectively the upper collar 23 and the means 24 for manually rotating the torque arm 20. Said means may take the form of a crank having an internally threaded bore at 25 to thread onto the threads 22 and which bore is axially open so that the wire 16 may extend therethrough as shown in FIGURE 1.

The tieing tool has a head 30 at its upper end which is adapted by means of threads 31 to unite with the collar 23 and thus be releasably connected to the torque arm 20 and has a hollow cylindrical or tubular portion 32 which complements the torque arm 20. A cap 33 having -a central aperture 34 is welded or otherwise secured on the upper end of the tubular portion 32. The aperture 34 is of a size to receive the wire 16 so as to form a bearing for the head on the main portion 16 of the tie wire 14.

A triangularly shaped hook support plate 35 welded or otherwise secured tangentially to the tubular portion 32 may extend on a radius thereof it desirable and supports, at a point radially spaced from the axis of the torque arm 20-32, a tail wire hook 36. The triangular hook support member 35 has a bead 37 extending substantially radially from the free end portion of the complementary torque arm portion 32 and terminating slightly spaced from the tail-wire hook 36.

The main portion 16 of the tie-wire 14 is caused to pass downwardly through the aperture 34 and the hollow center of the torque arm 20 and its complementary portion 32 and out the bottom of the crank 24. Manual rotation of the crank 24 causes the torque arm 20 to rotate and the hook support member 35 to move about until the tail wire 18 contacts the bead 37. Continuing rotation causes the tail wire 18 to attempt to slip over the end of the hook support member 35 and it thus becomes engaged in the hook 36 where the rotation of the torque arm 20 will cause the tail wire 18 to wind about the main portion 16 as seen at 19 and thus tie the tiewire to the support member 12.

In FIGURE 4 we have shown a modified form wherein the torque arm complementary portion 32 has a cross head 40 secured thereon and in which the aperture 34 is formed. The cross head 40 has tail-wire receiving slots 41 and '42 at opposed ends and its opposite edges constituting tail-wire hooks.

It will thus be seen that rotation of the torque arm 20 counterclockwise as seen at FIGURE 4 will effect Winding of the tail wire 18 about the main portion 16 similarly to the species of FIGURES 1-3.

Having thus described our invention we desire to secure by Letters Patent of the United States the followmg:

A hanger wire tie tool comprising an axially hollow cylindrical torque arm having releasable connecting means at each end for substituting various lengths of said arm; a manual crank releasably secured to one end of said torque arm by said connecting means and having an aperture axially aligned with the open center of said torque arm to receive and pass a tie wire therethrough; a head releasably secured to the other connecting means and having an open-ended tubular portion complementary to the torque arm; a substantially triangular hook support secured to said tubular portion and having a substantially radially extending bead thereon adjacent to the free end of the tubular portion for reducing frictional drag of a wire against said hook support; and a tail wire hook on the hook support at the outer end of said head.
